The technology sufficient to divert an asteroid, especially with limited warning(which precludes some of the subtler 'attach an ion drive or give it a slow shove with a laser' type schemes), is probably pretty punchy, possibly 'basically an ICBM but better at escaping earth's gravity well' punchy.

Not if you detect it far enough out. If you've got plenty of time, even a small force (e.g., from laser ablation) is quite enough to divert an asteroid well away from the Earth; it's amazing what a small force applied over a long time can do, especially if you've got negligible friction.

Like everyone else they don't know if anything was taken. And frankly, Heatbleed is probably the least of the security issues Healthcare.gov has... I'd be way more worried about backbend systems, and then it doesn't matter what your password is.

As I understand it, the majority of the implementation of healthcare.gov is Java. Java's SSL implementation doesn't have the heartbleed bug at all (and implementing this bug would actually take a lot more work than doing it right). If there's a problem, it's most likely in a front-end load balancer; I don't know if you'd see a lot of user credentials in that case, as the damage wouldn't be in systems that handle client authentication.

The database(s) might be affected too, but you probably can't reach them from a normal system; the heavily firewalled approach is a favorite of Big Software Contractors and is actually right in this case. I suppose if they were affected, processing the update to them (carefully as you don't want to lose data!) would count as preventative treatment while still properly supporting the assertion that no real damage was done.

The same ethyl alcohol is used for vodka, gin, rum, scotch, bourbon, brandy, tequila, Canadian whiskies, and liqueurs. MGP also sells some ethyl alcohol for fuel use, although for them it's a sideline, not their main business.

What a lot of brands I'd never heard of. Some of them have names that are confusingly similar to ones I've encountered, but not one is actually a known brand to me.

But at least some of the things are aged properly in the time between the bottle being filled and it leaving the plant. I mean, it's gotta be all of a few minutes!

Lecturing is an ineffective way to teach because most people cannot pay attention to and retain a traditional lecture.

That's why students are told to take notes. That's why students are told to study outside lectures; tutorials and — where appropriate for the course — practical sessions in labs reinforce the lecture. You don't learn by just listening to someone, but it is part of how you learn.

A site-license of almost any software will be a negliegable part of your operating budget.

It depends on what the software is. Some things are genuinely expensive, enough that while maybe a Fortune 500 can handle it, the many smaller companies out there tend to swoon at the prices charged. (These pieces of software tend to be in areas without major OSS competition.)

But a 400W LED fixture would produce nearly the same heat overall [as 400W HPS lights].

Well yes. Duh. All those watts have got to go somewhere, and that's virtually all going to be heat eventually. What matters is how much light you get for that power. And LEDs and HPS are fairly similar (enough that the details of exactly what you're doing and how they were manufactured matter; the luminosities per unit power are similar, according to Wikipedia).
